The conventional approach to constructing a three-dimensional distribution of the Earth's masses involves using Stokes constants incrementally up to a certain order. However, this study proposes an algorithm that simultaneously considers all of these constants, which could potentially provide a more efficient method. The basis for this is a system of equations obtained by differentiating the Lagrange function, which takes into account the minimum deviation of the three-dimensional mass distribution of the planet's subsoil from one-dimensional referential one.

Analytical and experimental investigations of influence of reverberation disturbances on measuring exactness of speech signal levels distributing function has been made.

The dissolving process of benzoic acid polydisperse mixture in the gas-liquid flow has been examined. On the basis of criterial dependence and the theory of local isotropic turbulence the mass-transfer coefficient was determined experimentally and theoretically and their values were compared. Theoretical calculation of polydisperse mixture dissolution was performed during periodic dissolution under variable driving force. Theoretical and experimental results were compared.
